Description
The Black Holy Grail draws on Tom Rosenbauer's pattern, offering a dark caddis pupa profile for trout feeding beneath the surface. Try it during caddis activity or as an alternative to lighter pupa patterns. Drift it through riffles and current seams, adjusting depth first, then testing a gentle lift or swing to suggest an ascending insect. Sold by the dozen for fly shop caddis assortments and guide boxes.
